Sylvania CFL Bulb - 9W | 4100K | G23 | Pack of 50

CF9DS/841/ECO (20305/21270) is the Sylvania CFL Bulb in the 9W, 4100K configuration. This model is for a fitting designed around this compact fluorescent lamp format. The keyed base and available lamp space are important when replacing a lamp in a downlight or task fitting.

The G23 base must match the exact keyed lampholder; a different pin arrangement is not interchangeable. Choose 4100K when that colour matches neighbouring lights in the lit area; this choice does not by itself establish the required brightness. The fitting’s ballast must be rated for this model and its lamp wattage. Order quantities are in packs of 50 for this model.

Buying tip: Check the existing socket for the G23 base and compare the available clearance with the lamp dimensions.
